# Introduction In this challenge, we will be implementing a web-based PowerPoint presentation (PPT) using front-end technologies. The purpose of this lab is to create a PPT that can be played in a browser, making it more convenient for dissemination and viewing. The specific objective is to switch PPT pages based on an active index and update the page number accordingly, while also adding appropriate classes to disable the "Previous" and "Next" buttons when necessary.
